I tested the camera after it had been immersed in the 10' pool overnight, and it still works. However, the megohm meter now reads < 10MOhms which is an electrical failure. So where's the problem? In turns out that the front of the camera is not seal as well as it could be - in fact that's kind of obvious from the photos when you look at them. I needed to find a better, but simple, way to seal this part.
